Grid-connected electric transport

Electric transport that is powered by an electricity grid.

Existing examples include:

  • Electric trains [to do: list the two or three largest networks here, with links to their Wikipedia articles if appropriate].
  • Trams [to do: maybe list largest networks].
  • Buses [to do: maybe list largest networks].
  • [Any other major examples?]

Relative to other comparable forms of electric transport, grid-connected transport typically:

  • Has a lower unit cost per vehicle, due to reduced need for vehicle-level energy storage and complexity.
  • Has a higher infrastructure cost, due to the need for electricity transmission and supply along the route.
  • Is much more constrained to particular routes, due to infrastructure requirements.
  • Can have greater efficiency, as vehicles carry reduced load related to energy storage and conversion.


Grid-connected electric transport has been in large scale service for [many decades], but nowhere near it's potential.

[Information on the feasibility of the method. One extreme may be many decades of proven track record on an industrial scale throughout the world, such as shipping. The other extreme may be an idea which is expected to have practical shortcomings such that it is unlikely to be the preferred method in any worthwhile use case, such as solar roadways.]


[Information on the impacts of the method, quantified where possible. This includes negative impacts, such as harm to the environment.]
